2. Linear algebra is a branch of mathematics, and its research objects are vectors, vector spaces (or linear spaces), linear transformations and linear equations with finite dimensions;

3. Calculus, mathematical concepts, is a branch of mathematics that studies the differential and integral of functions and related concepts and applications in higher mathematics. It is the basic subject of mathematics.

Extended data:

Calculus is a general term for differential calculus and integral calculus. It is a mathematical idea, in which' infinite subdivision' is differential and' infinite summation' is integral. Infinity is the limit, and the thought of limit is the basis of calculus, that is, to look at problems with a moving thought.

Linear algebra has various important applications in mathematics, physics and technology, so it occupies a primary position in all branches of algebra. With the wide application of computers today, computer graphics, computer-aided design, cryptography, virtual reality and other technologies all take linear algebra as a part of their theoretical and algorithmic basis.
